## JSONAsString {#jsonasstring}
In this format, a single JSON object is interpreted as a single value. If input has several JSON objects (comma separated) they will be interpreted as a sepatate rows.
In this format, a single JSON object is interpreted as a single value. If the input has several JSON objects (comma separated) they will be interpreted as separate rows.
This format can only be parsed for table with a single field of type [String](../sql-reference/data-types/string.md). The remaining columns must be set to [DEFAULT](../sql-reference/statements/create/table.md#default) or [MATERIALIZED](../sql-reference/statements/create/table.md#materialized), or omitted. Once you collect whole JSON object to string you can use [JSON functions](../sql-reference/functions/json-functions.md) to process it.

## JSONAsString {#jsonasstring}
В этом формате один объект JSON интерпретируется как одно значение. Если входные данные имеют несколько объектов JSON, разделенных запятой, то они будут интерпретироваться как отдельные строки.
В этом формате парситься может только таблица с единственным полем типа [String](../sql-reference/data-types/string.md). Остальные столбцы должны быть заданы как [DEFAULT](../sql-reference/statements/create/table.md#default) или [MATERIALIZED](../sql-reference/statements/create/table.md#materialized), либо отсутствовать. Как только вы соберете весь объект JSON в строку, для его обработки вы можете использовать [функции для работы с JSON](../sql-reference/functions/json-functions.md).
**Пример**
Запрос:
``` sql
DROP TABLE IF EXISTS json_as_string;
CREATE TABLE json_as_string (json String) ENGINE = Memory;
INSERT INTO json_as_string FORMAT JSONAsString {"foo":{"bar":{"x":"y"},"baz":1}},{},{"any json stucture":1};
SELECT * FROM json_as_string;
```
Результат:
``` text
┌─json──────────────────────────────┐
│ {"foo":{"bar":{"x":"y"},"baz":1}} │
│ {} │
│ {"any json stucture":1} │
└───────────────────────────────────┘
